For as long as I've had Mixbus installed I've never seen any horizontal or vertical scroll bars in the region canvas. The manual alludes to the fact that they're there, but they're certainly not there on my version and the only way I can horizontally scroll is either with the summary view or the scroll wheel. Does anyone else have them, am I going mad? 

The side to side scroll bar is at the bottom of the TV over all those colored lines (the shaded area). Is that what you need?
 

Yeah I see that summary view which is like the navigator in Sonar, but it disturbs me that the manual references something which isn't there (and it does seem kind of weird that there wouldn't be scroll bars in a clips window).

The manual also references a colored bar at the bottom of each clip too, and that's not there either. However when I look at screenshots of earlier versions the clips do have that bar. Looks like they did away with them and didn't bother updating the manual.
